掺杂Lu2O3对Ba4Sm9.33Ti18O54微波介质陶瓷性能的影响
Effects of Lu2O3 doping on the performance of Ba4Sm9.33Ti18O54 microwave dielectric ceramics
摘要
Abstract
Doped Lu2O3Ba4Sm9.33Ti18O54 microwave dielectric ceramics were studied in order to improve dielectric performance of the ceramics. The solid solution formula was Ba4(Sin1-yLuy)9.33Ti18O54. The results show that the sintering temperature of BaSm9.33Ti18O54 microwave dielectric ceramics is reduced to 1 260 ℃ effectively by doping Lu2O3. When y=0.05, the major phase BaSm9.33Ti18O54 was similar to tungsten bronze type structure and the dielectric performance of Ba4(Sin1-yLuy)9.33Ti18O54microwave dielectric ceramics is more excellent: at 4.33 GHz, εr=76, Q ·f=2532, τf=-42×10-6 /℃. When y<0.5, there is BaSm2Ti4O12 phase; while y≧0.5, the main phase become pyrochlore phase and it does not behave dielectric properties.关键词
